The GASMAX ECx wireless gas monitor
delivers the latest in toxic gas detection
technology, reliability and ease of use.
The GASMAX / ECx is designed for use
in hazardous or explosion proof installations.
Wide Variety of Available Sensors
The GASMAX ECx support all GDS
Corp toxic sensors; in addition, GDS Corp
Smart Sensors enhance this capability
by maintaining their own record of serial
number, born-on date, initial calibration values, engineering units and more.
Using this information, the GASMAX
ECx constantly tracks sensor performance
and calculates an estimate of sensor life
remaining.
Advanced User Interface
The highly visible display and alarm
LEDs constantly show status, calibrated
engineering values and a programmable
tag name; a trend screen shows alarm
levels and the most recent 30 minute
data values. An internal real-time clock
and event log time-stamp calibration and
alarm events for later review. A menu-
driven operator interface using magnetic
keys eliminates all analog potentiometers
and allows complete setup and calibration
without hazardous area declassification.
Fully Integrated Wireless Solution
An internal D-cell lithium battery and
900Mhz or 2.4Ghz license-free spread-
spectrum wireless modem provide up to
six months of continuous operation in
typical applications. Every 6 seconds, the
GASMAX ECx samples the atmosphere
and transmits a warning signal if the
pre-programmed alarm level is exceeded.
Under normal conditions the GASMAX
ECx transmits a ‘keep-alive’ signal
periodically to verify communications and
advise the controller if the battery is low.
Host Controllers
The GASMAX ECx is designed to operate
with the C1 Protector 8/16 channel
controller / receiver, the C2 Quad
Protector 4 channel controller / receiver
or the C64 Protector multi-channel
controller. Controllers are available with
integrated 900Mhz or 2.4Ghz wireless
modems.

Determining Wireless Communications Range
The distance at which any wireless connection will operate reliably is dependent on
many factors, including terrain, frequency, path length, interference from existing
radio sources, combined antenna height, transmitter power and receiver sensitivity. For reliable communication, the system power margin (TX power + RX gain +
Antenna gain - Path Loss) must exceed 20 dB. Range can be improved by increasing
antenna height, using directional antennas or increasing transmitter power. Contact GDS Corp for more information.
